Unit 1 - Number

Unit 1 lays the foundation for success in IB Math AI. The resources here are carefully aligned with the official IB syllabus and written to mirror the types of reasoning, vocabulary, and problem structures students encounter on the IB exam. Each subtopic—whether it's arithmetic sequences, geometric decay, or financial modeling—is developed with both conceptual depth and test-readiness in mind. From guided notes and student-friendly explanations to IB-style questions and assessments, every component is classroom-tested and designed to build confidence, fluency, and real-world understanding.
